Make the drive to RI and you will pay a lot less. RI has many art schools and many glass blowers. I've found prices to be a lot cheaper in most shops in RI. I always go out of my way to go to this place: Ethnic Concepts Smoke Shoppe - glass pipes and smoking accesories
Its like right off of the highway so its simple to get to. A bit small but tons of nice stuff and cheap stuff is packed into this little shop. If your into really fancy expensive glass this is the place for you.
